SANDING DEVICE, AND SANDING ASSEMBLY INCLUDING THE SAME
Field of the invention:
The present invention relates to a sanding device, hereinafter referred to
also
as a "sanding tool". More particularly, in its preferred intended use, the
present
invention relates to a sanding tool such as the ones used with extensions
poles,
vacuum systems and the like, and also relates to a vacuum/sanding assembly
provided with such a sanding tool, and to a method of operating associated
thereto.
Background of the invention:
Known in the art are various tools used for sanding applications and other
related tasks.
The Assignee of the present application has developed several of such
products, some of which are described in the following US patents and

Indeed, sanding tools are very well known in the art. A typical sanding tool
usually comprises a handle for manual operation of the tool and a working or
operating surface onto which a sandpaper (or a sanding meshing) is mounted and
rested so as to be able to carry out sanding applications by passing the
sandpaper-
covered operating surface over the area to be sanded.
Also known in the art are the fastening devices which are commonly used to
removably mount a sandpaper onto such a sanding tool. Indeed, a typical
fastening
device generally consists of a pin projecting from a rear portion of the
sanding tool
onto which a clamping plate is pivotally mounted. A portion of the sandpaper
is
generally clamped between the rear portion and the clamping plate and this is
generally achieved by urging the plate against the rear portion of the sanding
tool by
means of a nut threadedly engageable onto the pin and rotated thereabout so as
to
bias the clamping plate against the rear portion. The nut is usually provided
with a
pair of projections which are commonly known as "rabbit ears" and which are
used
to facilitate the rotation of the nut about the threaded pin with the fingers
of an
operator of the tool.
Furthermore, it is also known that most conventional sanding devices that are
not used with vacuum systems do not enable a proper evacuation of sanded
particulars from either the operating surface of the tool or from the surface
being
worked on by said tool, and that even some conventional sanding devices that
are
used with vacuum systems present significant shortcomings in terms of sanding
results (ex. performance, efficiency, etc.) and in terms of suction and/or
evacuation
of sanded particles (ex. during use in hard-to-reach places, etc.), and in
terms of
maneuverability (range of motion, flexibility of sanding possibilities and
angles, etc.).
CA 2919879 2017-09-27

Moreover, although the present invention was primarily designed for use with
a sanding paper/meshing for carrying out sanding applications, preferably in
conjunction with an extension pole, a vacuum system and/or the like, it may be
used
with other objects and/or in other types of applications, as apparent to a
person
skilled in the art. For this reason, expressions such as "sanding", "paper",
"meshing",
"extension", "pole", "vacuum", etc., used herein should not be taken so as to
limit the
scope of the present invention and include all other kinds of objects and/or
applications with which the present invention could be used and may be useful.
Moreover, in the context of the present invention, the expressions "tool",
"device", "system", "sander", "unit", "assembly", "product", as well as any
other
equivalent expressions and/or compound words thereof, may be used
interchangeably. The same applies for any other mutually equivalent
expressions,
such as "paper" and "meshing" for example, as well as "base", "plate" and
"handle",
or even "fastener" and "pin", as also apparent to a person skilled in the art.
Furthermore, in the context of the present description, it will be considered
that all elongated objects will have an implicit "longitudinal axis" or
"centerline", such
as the longitudinal axis of a fastener or a tube (ex. joint), or the
centerline of a bore,
for example, and that expressions such as "connected" and "connectable", or
"mounted" and "mountable", may be interchangeable, in that the present
invention
also relates to a kit with corresponding components for assembling a resulting
fully
assembled and operational sanding device (1).
In addition, although the preferred embodiments of the present invention as
illustrated in the accompanying drawings comprise various components, and
although the preferred embodiments of the sanding device (1) and corresponding

parts as shown consist of certain geometrical configurations as explained and

illustrated herein, not all of these components and geometries are essential
to the
invention and thus should not be taken in their restrictive sense, i.e. should
not be
taken so as to limit the scope of the present invention. It is to be
understood, as also
apparent to a person skilled in the art, that other suitable components and
cooperation thereinbetween, as well as other suitable geometrical
configurations
may be used for the sanding device (1) and corresponding parts according to
the
present invention, as will be briefly explained herein and as can be easily
inferred
herefrom by a person skilled in the art, without departing from the scope of
the
present invention.

tube
(69), the supporting tube being rotatable about said mounting pin (51).
The first end (71) of the supporting tube (69) may comprise at least one
mounting flange (75,77) for mounting about the mounting pin (51) of the joint
(29) so
as to allow the supporting tube (69) to rotate with respect to said joint
(29).
According to a possible embodiment, the first end (71) of the supporting tube
(69) comprises first and second mounting flanges (75,77) for mounting about
the
mounting pin (51) of the joint (29) so as to allow the supporting tube (69) to
rotate
with respect to said joint (29), with the mounting pin (51) defining the
second axis of
rotation (95), and a first end (71) of the supporting tube (69) being open-
ended, and
a second end (73) of the supporting tube (69) being open-ended, as well, for
example.
The second end (73) may be provided with a socket (79) for receiving a
complementary tool (123) (ex. an extension pole, a hose of a vacuum system,
etc.).
According to a possible embodiment, the supporting tube (69) comprises a
tapered section (81) between its first and second ends (71, 73).
The supporting tube (69) may comprise a peripheral hole (83) for receiving a
corresponding component (ex. fastener) meant to cooperate with a complementary
tool (123).
The sanding surface (5) of the base plate (3) may comprise a central portion
disposed between a pair of side portions, with the central portion of the
sanding
surface (5) comprising a higher concentration of orifices (17) than that of
the side
portions. Also, orifices (17) of the central portion of the sanding surface
(5) may be
CA 2919879 2017-09-27

17
generally narrower than the orifices (17) of the side portions, although
various
configurations and layouts are contemplated with the present sanding device
(1).
Various manufacturing and/or assembling methods may be used, but
according to a possible embodiment, pins (ex. mounting pin, guiding pin, etc.)
of the
sanding device (1) are press-fitted into corresponding holes (ex. bores,
etc.).
As may now better be appreciated, the present invention is a substantial
improvement over the prior art in that, by virtue of its design and
components, as
explained herein, and the particular configuration of the joint and sealing
members
thereof, the sanding tool according to the present invention enables for a
quicker,
easier, simpler and more effective manner than what is possible with respect
to other
sanding tools available in the prior art.
Indeed, among the different advantages resulting from the present sanding
device, the particular design of the joint and sealing members (ex. with
flexible
hinges), in the manner in which they cooperate with the supporting tube, as
can be
easily understood by a person skilled in the art, in the light of the
preceding
description and accompanying drawings, enable a vacuum chamber to be created
inside the rotatable joint, when the sanding device is used with a vacuum
system, for
example, so as to enable for improved sanding results in term of performance,
efficiency, surface quality finish, etc.), and also in terms of suction and/or
evacuation
of sanded particles, irrespectively of the positioning (ex. rotational angle,
etc.) of the
rotatable joint and/or of the pivoting supporting tube, etc.
In ending, the scope of the claims should not be limited by the preferred
embodiments set forth in the examples, but should be given the broadest
interpretation consistent with the description as a whole.
